The ELCAN SpecterDR Dual Role Optical Sight represents a revolution in optical sight design. The world’s first truly dual fieldof view combat optical sight, the SpecterDR switches instantly from a 4x magnified sight to a 1x CQB sight with the throw of a lever. Unlike zoom sights, the SpecterDR offers an optimized optical path and identical eye relief in both 4x and 1x modes. Depending upon the situation, the user may adjust the sight to illuminate the entire crosshair or just a brilliant red dot in the center. In 4x mode the SpecterDR offers a generous field of view, long eye relief, and ELCAN’s legendary crystal clear image. In CQB mode, the SpecterDR has by far the largest field of view in the industry. The 4x and CQB Reticles are plainly visibleeven in the case of loss of electrical power due to battery failure or EMP.The SpecterDR offers the best single solution for Long Range and CQB engagements and is designed to withstand the rigors of modern professional use.
